HERSCHEL OATON. OF KANSAS CITY, MISSOURI. PERFORATING ATTACHMENT FOR PRlNTlNG-PRESSES.

Specification of Letters Patent.

Patented May 22, 1906.

Application filed June 8,1905. Serial No. 264,262.-

To all whont it 777/607] concern:

Be it known that I, HERSOHEL OAToN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Perforating Attachments for Printing-Presses; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilleddn the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My present invention relates to a perforating attachment for printing-presses, and has for its object to provide a device of the class described which may be easily and quickly mounted on a cylinder printing-press in such a manner as to perforate the sheets of paper as they travel in their usual course through the press.

My invention consists in the improved details of structure of the perforating attachment and in the novel combination thereof with the parts of the printing-press, all of which will presently be fully described, and pointed out in the claims, reference being had to the accompanying drawings, forming part of this specification, in which like referencenumerals refer to like parts throughout the several views, and in which- Figure 1 is a longitudinal vertical section of such parts of a cylinder printing-press as are required to illustrate my invention. Fig. 2 is a top plan view showing the cylinder, the stay-rod carrying the perforating-rollers, and

the fly-shaft with its pulleys and idlers. Fig.

3 is an enlarged view, in side elevation, of the perforating attachment. Fig. 4 is a similar view of the bracket carrying the perforatorarm. Fig. 5 is a similar view of the perforator arm and disk.

Referring more in detail to the drawings,

6 is the cylinder, 7 the type-bed, and 8 the feed-table, of an ordinary cylinder-press. Extending across above the cylinder and secured in the sides of the press is the rod 9, on which is rigidly mounted a yoked bracket 12, in which is journaled the roller 13, adapted to bear against the cylinder 6 to guide the sheet as it passes into the press.

10 is the fly-shaft, on which are mounted the fly-pulleys 14 and the idlers 15, over which the sheet passes as it leaves its contact with cylinder 6.

Rigidly mounted on shaft 11 adjacent to rod 9 is a bracket 16, comprising the outwardly-projecting arm 17, the circular flange 18, and the semicircular-flanged socket 19, having the cap 20, adapted to fit around shaft 11 and be bound to socket 19 by the screw-bolts 21.

Pivoted to a lip 22 on flange 18 is the arm 23, carrying in a yoke in its free end the serrated perforating-disk 24. The inner end of arm 23 is curved, as at 25, and is provided with a groove 26, adapted to fit over a portion of flange 18 for the purpose of retaining saidarm in the desired position in relation to the bearing for disk 24. Pivoted on. the pin 27, extending through the arms of the yoke in arm 17, is a ring-bolt 28, which extends upwardly through a perforation in an arm 23 and carries a thumb-nut 29. Seated on arm 17 and bearing against the under surface of nut 29 is a coil-spring 30, which serves to yieldingly retain arm 23 and disk 24 in their correct position with respect to the press parts.

In the use of my device when a job requiring perforating is put on the press one or more of the attachments are secured on shaft 11 in a position to bring the disk 241 in line with the desired line for perforation and the idlers 15 arranged in position to contact with the disk. By means of nut 29 the tension of spring 30 may be regulated to suit diflerent conditions of work. As the sheet is fed into the press it is carried around by the cylinder and then delivered to the fly, which carries it between the disks 24 and idlers 15, the tension on said disk being so regulated as to perforate the sheet during such passage.

While I have specifically described my in vention, I do not wish to be understood as limiting myself to the exact details of structure therein shown and described, inasmuch as the same may be varied without departing from the spirit of my invention.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

1. In a perforating attachment for printing-presses, the combination of the cylinder, the delivery fly-shaft, fly-wheels and an independent smooth-rimmed wheel carried by said fly-shaft, a rod extending transversely above the cylinder, a bracket carried by said rod, and a perforating-disk carried by said bracket in engagement with the rim of said independent wheel.

2. In a perforating attachment for printing-presses, the combination of the cylinder, the delivery fly-shaft, fly-wheels and an independent smooth-rimmed wheel carried by said fly-shaft, a rod extending transversely above the cylinder, a bracket rigid on said rod, a semicircular flange 18, having an ear 22, on said bracket, an arm having a forward forked portion, a semicircular grooved rear portion on said arm fitting over flange 18, a plvot-pin extending through perforations in the curved portion of said arm and through a perforation in ear 22, a bolt pivoted to the forward end of said bracket and extending upwardly through a perforation in said arm, I 5 a coil-spring around said bolt above said arm, a thumb-nut on the loose end of said bolt, and a disk journaled between the forks of said arm and held in en 'agement with the rim of said independent W eel on the delivery fly-shaft.

In testimony whereof I aflix my signature in presence of two witnesses.
